Entitled "The Big Four Live From Sofia", the DVD sees the band perform alongside Slayer, Megadeth and Anthrax in a concert they played in Bulgaria in June this year.
"The Big Four Live From Sofia" includes the entire sets of all four bands on a two disc set as well as behind the scenes and exclusive interview footage.
Metallica commence their nationwide tour on September 15 in Melbourne.
